NEW YORK, N. Y.
new era in concrete engineering opened
when 'Incor' 24-Hour Cement was introduced,
in 1927. Improved manufacturing methods had
reduced the time required for concrete to at-
tain service strength — and 5 to 7 days' curing
then accomplished what had taken 10 to 21
days a decade before.
But the makers of Lone Star Cement saw
the need for a true Portland Cement which
would cure or harden thoroughly in 24 hours,
and pioneered in this further forward step.
That was ten years ago. Today the strength
and durability of 'Incor' concrete have been
proven by a decade of use. Many miles of con-
crete paving and hundreds of concrete struc-
tures attest both the high early and high ulti-
mate strengths of this improved Portland
The record of service here presented shows
that 'Incor' is producing the same kind of con-
crete that skilled contractors have been making
with Lone Star Cement ever since 1900. For
behind 'Incor' stands Lone Star's 37-year rec-
ord for high quality and unvarying uniformity.
FOR A DECADE, 'Incor' concrete
walls and roof sections in Moffat
Tunnel have withstood pressures
as high as 10 tons to the square
foot. Shifting masses of earth and
rock have been held in check.
Ground waters have been effect-
ively blocked off— 'Incor' concrete,
placed in 1927, is watertight, dense,
impervious. Wood beams in other
sections of the tunnel required con-
stant repairs (cost, £75,000 a year)
and were finally replaced with con-
crete; but 'Incor' supports a moun-
tain—hasn't required a dollar's
worth of maintenance.

Proof of high early strength.
AFTER TEN YEARS
But what about ultimate strength and durabil-
ity? The ten-year record speaks for itself. For
a decade, Tncor' has held in check "the great-
est pressures ever encountered in rock-tunnel
work/' Running water, seeping down through
the mountain above, has been kept out. To
provide drainage, they had to bore through
While wooden beams in other parts of the
tunnel required constant repair and replace-
ment (cost, 275,000 a year), Tncor' supports a
mountain— hasn't required a dollar's worth of
maintenance since the day it was placed. Proof
of high ultimate strength and durability.
In September, 1927, Pennsylvania Railroad
completed an extensive relocating and double-
tracking project on the New York-Pittsburgh-
St. Louis main line. Bridge at Greenup, 111.,
was the last to be completed. Twenty to 30
trains a day were scheduled for the new route
—and savings to be obtained by the new dou-
ble track, elimination of highway crossings and
heavy grades, amounted to many dollars daily.
Mncor' was used for bridge-deck concrete.
Since 1928, 'Incor' paving at Main Street and Echo Avenue
intersection (right) of Boston Post Road, New Rochelle,
N.Y., has earned 20.000 vehicles a day, including New York-
New England traffic, with heavy inter-city trucking. Close-up

— 1296 lbs. per sq. in. higher than ordinary concrete, placed at
Tncor' cores averaged 6436 lbs. At these ages,
cores of the ordinary concrete tested 5516 and
6065 lbs., respectively.
Then, in October, 1928, City Engineers used
Tncor' to repave Washington and North
LaSalle Street intersection in Chicago's Loop
—traffic count 15,000 cars daily. Late on a
Saturday, Tncor' was placed on half the inter-
section. Weather was cold and sleet was fall-
ing, but this concrete was opened to traffic
first thing Monday morning. Ordinary con-
crete, used on the other half of the intersection,
was opened 7 days later. 'Incor' saved a pro-
longed traffic snarl.
In August, 1936, both concrete sections were
cored. Tncor' cores averaged 8696 lbs. per sq.
in.; the other concrete averaged 7400 lbs.
Illustrating the two-way advantage of Tncor'
Cement— both high-early and high-ultimate
strengths, with equal dependability.
RECORD IN HEAVY-
DUTY FLOOR SERVICE
In 1929, Tncor' began to attract attention of
factory-owners, dairymen, and others inter-
ested in longer-wearing, more watertight con-
crete. One of the first to make use of Tncor's
not-a-working-day-lost schedule of floor-re-
placement was Walnut Grove Dairy, Alton,
111. Floor slab then in use, badly cracked and
settled, required constant patching. Equally
important, a cracked floor cannot be properly
cleaned— and dairies must meet strict sani-
But business was good, and the floor could
not be kept out of use. Operations were plan-
ned to make full use of Tncor's high early
'Incor' enabled contractors to resurface this
dairy floor without interruprinf; plant opera-
tions. At moderate cost, the owner replaced a
worn-out, cracked, unsanitary floor— constant
source of trouble and expense-with one that
is smooth, sanitary, easily kept clean, and
hasn't cost a cent for maintenance in nearly 8
years of heavy-duty service

Pouring began at midnight; concrete was
tamped into place and properly finished; at
3 a.m., a day's work was completed. At 5 a.m.
the surface was hard; light boards were then
laid on the new concrete and plant operations
resumed. When the boards were removed,
within 24 hours, the 'Incor' surface was un-
marred— no marks even where filled milk cans
had been dragged off the boards and onto the
How did the floor stand up: Nearly 8 years
after the floor was resurfaced, careful inspec-
tion shows 'Incor' concrete to be good as new.
Exposed to milk spill, heavy cans rolled across
the concrete 19 hours every day— not a cent
for maintenance. Truly, heavy-duty concrete.
LOADING DOCK TAKES
A TERRIFIC BEATING
Cold-storage companies, creameries, laundries,
freight depots, packinghouses— plant operators
in general— demand plus values in concrete.
And they get it when 'Incor' is used for floor
slabs, loading docks, driveways and in other
places where both durability and strength are
essential. During construction, 'Incor' saves
expensive delays that tie up business; in serv-
ice, 'Incor' stands up under the daily grind,
giving years of expense-free service.
Case in point is the loading dock of Mutual
Ice & Cold Storage Plant at Topeka, Kan.,
constructed in September, 1928. Inspected 8
years later, the 'Incor' concrete was found to
be in perfect condition. Photograph, at top of

200 TRUCKS A DAY
FOR 7 YEARS -NO UPKEEP
'No maintenance required/' So, too, reads
the inspection report on eight 'Incor' driveways
built tor Central Cold Storage Company,
Chicago, in 1929.
Street level was being changed, and it was
necessary to rebuild sub-structures and paving
er a sidewalk-vault and basement. Six drive-
w ays had to be kept in constant use. With ordi-
nary concrete, each driveway would have been
out of service 16 days, counting time required
to wreck and replace supporting structures.
That meant nine weeks to complete the job.
With 'Incor', each driveway was placed in ser-
vice in 48 hours — the entire job took only two
weeks. Two advantages to the owner:
(1) Constant access to driveways — full use
of facilities almost two months sooner; (2)
longer-wearing concrete, no upkeep expense.
9 YEARS' SERVICE -
Indiana Railroad Company reports 78,000 toni
of freight passed over the Tncor' concrete load-
ing-platform at Indianapolis Freight Terminal
in the year ended August 31, 1936. It was less-
than-carload business— everything from oil
drums to portable garages— and put plenty of
pressure on the steel truck wheels. But the
'Incor' concrete platform floor, placed in 1927,
is still in excellent shape. Nearly 10 years'
service— no maintenance.
Reason for using 'Incor' : Old wood deck \\ as
badly worn, had to be replaced. There was no
other platform available, so the new structure
had to be built without interrupting service.
'Incor' solved the problem. On Saturday
afternoon the railway's construction gang be-
gan work. Early Monday morning the new
concrete was in use; not a working day lost;
no interference with freight service. And, as a
plus value, the concrete is in excellent condi-
tion today, good for many years to come.
WATERTIGHT SINCE 1929
-IN A COAL MINE
After ten years, many structures which keep
water in or out, clearly demonstrate the greater
watertightness of well-made 'In< ncrete.
Case in point is the mine shaft of Mercantile
Coal & Mining Co., Richmond, Mo. Quicksand
and water 50 feet below surface made timber
bracing ineffective. Ordinary concrete gained
strength too slowly, so 'Incor' was used.
Concrete was placed in four-foot sections.
When the shaft extended above the surface,
the concrete lining was forced down with a 30-
ton weight. A cave-in at the 70-foot level threw
the shaft six feet out of plumb. Two hundred

tons pressure was applied to force the shaft
back in place— without concrete failure.
For more than seven years, pressures of water
and quicksand have been held in check. "Still
watertight," reports F. R. Atwill, Manager,
Mercantile Coal & Mining Company— still
watertight, without a dollar for waterproofing
EXPOSED TO SEA
FOR 8 YEARS
Today, engineers also specify Incor' for con-
crete exposed to salt-water action, because ex-
perience shows that 'Incor' concrete, properly
made, is not only inherently watertight, but
successfully withstands the chemical action of
In 1928, when Tampa, Fla., Union Terminal
was constructed, 'Incor' was used because it
also offered a cheaper method of constructing
dock piling and slabs. Behind-schedule con-
struction of a 200-ft. section of the dock threat-
ened to delay opening. Delay meant interfer-
ence with shipping — and tying up a $3,000,000
investment. Tncor' put the job backon schedule.
'Incor' concrete piles, lifted three days after
casting, were driven to refusal 24 hours later,
without sign of fracture. Dock work followed
immediately, with forms stripped four days
after pouring. Result, job completed 21 days
sooner— saving #10,000 in job overhead and

Concrete car-track paving, placed by Topeka,

laid. About 1200 vehicles an hour pass over
this concrete. On October 5, 1936, Kansas

Canal Street, New Orleans, scene of Mardi Gras. 'Incur' repaving without traffic interruption, saved mer-
chants $200,000 trade loss in 1929. No upkeep expense, concrete good as new, after 8 years' hard wear.
MERCHANTS SAVED $200,000
-NOT A CENT FOR UPKEEP
To tie up Canal Street, New Orleans, at Mardi
(iras time would be like barricading New York's
Broadway on New Year's Eve. Yet, in Decem-
ber, 192V, New Orleans contracted to repave
Canal Street from Claiborne Street to the River
— 18 blocks of paving, with 21-ft. sidewalks.
Merchants demanded quick action. Forty-
nine thousand square yards of pavement and
45,000 square yards of sidewalks and neutral
zone paving had to be constructed — but con-
structed with "business as usual." Ordinary
Portland cement meant several months of de-
moralized business; traffic would have to be
re-routed; and Mardi Gras, only a few weeks
off, intensified the problem.
So Tncor' was used throughout the job.
Paved a section at a time — opened the next
day — concrete work went forward rapidly.
Each block was finished 11 days sooner. Car
service was normal. Merchants estimated Tncor'
saved them at least 3200,000 net profit on sales
that would have been lost had the street been
barricaded while ordinary concrete hardened.
Today, after more than 7 years, taxpayers
share merchants' satisfaction — for the Tncor'
concrete is good as new — not a cent for main-
SO, BETTER CEMENT
DOES MAKE BETTER CONCRETE
Low night temperatures prevailed, back in Oc-
tober, 1928, when New York Central Railroad
station plaza at Ossining, N. Y., was repaved
with 'Incor.' To avoid traffic tie-up, paving
was laid in 70 sections, each section opened to
traffic in 24 hours. A huge electric transformer
was trucked over 36-hour-old 'Incor' slabs
without damage to the freshly-placed concrete.
Entire job was completed in 10 days — 30 days
sooner than possible with ordinary concrete.
In spite of heavy traffic, 'Incor' concrete is as
smooth and sound as opening day. And that,
in a nutshell, is the service record of 'Incor' in
all classes of construction, under pitiless wear
and gruelling exposure. For these are not hand-
picked jobs— they are fairly and squarely typi-
cal of the kind of service 'Incor' is giving.
Truly, then, this better Portland cement
does make better concrete.

WHAT THE RECORD PROVES
The ten-year record of 'Incor' 24-Hour Cement surprises no one
who is familiar with the care and skill with which the product is
made. For durability and uniformity are built into the cement at
the factory. Before a single barrel of 'Incor' was ever shipped,
laboratory investigations showed that 'Incor' concrete would have
exceptional strength and wear-resistance. The test of time now
confirms these findings. In brief, here is what this record of a dec-
ade of service means to the specifier and user of concrete.
L 24-HOUR SERVICE STRENGTH -Reduced caring costs . . . Faster fol-
low-up operations . . . Marked winter economies.

The net of it is that 'Incor* has made concrete a ready-to-use con-
struction material-at the same time providing in finished com rete

"TO MAKE SURE IT'S WATERTIGHT"
"To make sure of getting a watertight structure in a residential district and prevent leakage that might flood basements
of nearby homes," was New Haven, Conn., Water Company's stated reason for using 'Incor' for Mill Rock Reservoir. In
5 years since completion, 'Incor' has made assurance doubly sure— concrete in excellent condition. Illustrating how 'Incor'
helps assure watertightness-by curing thoroughly in short time concrete can be kept wet: 24 to 48 hours with 'Incor*,

PILING AND PRODUCTS
PILING DRIVEN 3 WEEKS EARLIER, curing period reduced 70%, saved 20 days in erecting
Louisiana's 33-story Capitol building, Baton Rouge, housing all State government departments.
Earlier occupancy saved 320,000 in rentals. Typical of 'Incor's advantages in pre-cast concrete work.
CAST IX 1929, incor' transmission poles (below^) are in excellent condition today—
"Good as day it was cast," reads suruv report. First poles built with Mncor', tested
m 4^ hours, exceeded resulti previously attained at 6 months, so manufacturer
switched to 'Incor*. Ultimate as well as early aJ\antages amply jusnhed the action.
DRIVEN WHEN 5 DAYS OLD-2 weeks sooner than ordi-
nary concrete— 'Incor' piling for Kansas City (Mo.) Power &
Light Co. garage (above) withstood 90 blows from 5000-1 b.
hammer after pile-point reached bedrock. Shaft was sunk par-
allel to one of 495 piles, to get "low-down" on condition. Photo

CONCRETE FRAME ERECTION
The frame is the only part of a building where work can be speeded up without increasing costs — and usually at substan-
tial savings. This principle, established by 10 years' experience, is illustrated by various structures at Louisiana State
University, Baron Rouge. In Field House, shown below, Tncor' saved 30 days' job overhead and the cost of one form-set —
total saving, #4200. 1 his building gets strenuous wear; all concrete in perfect condition, after 7 years' service.
ON WALL-BEARING as well as con-
crete-frame stucrures, 'Incor' shows sub-
stantia! savings. West wing of Methodist

■el of formt, jumped up from floor to floor
in 24 to 4S hours. Saved one extra form
set, and concrete kept ■head of brick-
layers. Job completed 20 days sooner, with
corresponding saving in overhead. FloOfl

BRIDGES: BETTER CONCRETE AT LOWER COST
Arlington Memorial Bridge, Washington, D. C, where 'Incor', used in key-ways, made it possible to release forms 10 days
looner. Faster form re-use meant substantial savings. In 10 to 12 hours, 'Incor' concrete was strong enough to resist move-
ment of steel falsework due to temperature change— avoiding serious structural hazard. At one and two days, 'Incor'
provided strengths equal to 10 days with rich-mix ordinary concrete. Typical of 'Incor's ten-year record in bridge construc-
tion—lower costs, smoother operation, faster turnover. And better concrete, cured thoroughly in one-fifth the usual time.
'INCOR' SAVED 12 DAYS, S300—
when used on abutments, footings and
arch of Fowler River Bridge (right),
Bristol, N. H., enabling contractor to
avoid contract penalty. Placed in 1930,
all concrete in excellent condition.

HENCE, THIS TIMELY SUGGESTION
A structural material is only as good as the men who use it. That
being so, it follows that this ten-year record of the strength, durabil-
ity and economy of 'Incor' 24-Hour Cement is, first of all, a tribute
to the architects, engineers and contractors whose skill is here re-
flected. To these men we express thanks and appreciation. This
decade of experience with 'Incor* may be summarized briefly, as
1. REDUCED CONCRETING COSTS— Service-strong in 24 hours, 'Incor*
does away with non-productive time waiting for concrete to harden, re-
duces forming costs, promotes smoother, steadier job operation. 'Incor'
also moves into place easier, gives greater workability, helps to reduce
9. BETTER JOB-CURED CONCRETE -'Incor' cures thoroughly in 24 to
48 hours, instead of 8 to 10 days. That means reduced curing costs and
thorough cunng in the short time concrete can be kept wet; better-looking
concrete, with less finishing— stronger, denser, more watertight concrete.
I. KNOWN DEPENDABILITY-When 'Incor' was introduced, the con-
struction industries accepted it with confidence, because behind 'Incor*
stood Lone Star's record for outstanding quality and unvarying uniformity.
Now 'lncor's ten-year service record merges with the 35-year record of
Lone Star to provide an even greater measure of assured dependability.
Hence, this timely suggestion: Estimate the dollars-and-cents value
of 'lncor's early strength and rapid curing. When it shows you a
profit, use *Incor\* Otherwise, use Lone Star. You gain either way
— because better cement makes better concrete
